Dear all, I am refering to this tutorial when trying my dot matrix.
" so a column needs to be high for any of the LEDs in that column to turn on. The rows are connected to the LEDs anodes, so the row needs to be low for an individual LED to turn on. "
For this, I do not understand it. I think it should be the reverse ? Hope someone can clarify to me and anyone knows how can I test my new bought dot matrix to ensure all the LEDs light up at the same brightness ?
Thank you in advanced :)
